BACKGROUND: In a minority of patients with neuromyelitis optica spectrum disorder (NMOSD) and aquaporin-4 antibodies (AQP4-IgG), the disease has a paraneoplastic origin. It is unknown whether these patients have distinctive clinical features. OBJECTIVE: To report the clinical features of a series of patients with paraneoplastic NMOSD and AQP4-IgG and to review previously reported cases. METHODS: Retrospective analysis of clinical records of 156 patients with NMOSD and AQP4-IgG and review of previously reported patients with paraneoplastic NMOSD and AQP4-IgG...

Melanoma is a highly prevalent cancer that is associated with substantial mortality. Although clinical staging procedures can serve as relatively robust prognostic indicators, we aimed to determine whether assessments of the abundance of hypoxia inducible factor-1α (HIF-1α) or vascular endothelial growth factor (VEGF) in postexcisional melanoma tumor tissues may enable more accurate determination of tumor aggressiveness. We carried out a multicenter prospective study, in which we systematically evaluated 376 consecutive patients diagnosed with melanoma, and performed histochemical assessments for both HIF-1α and VEGF immunoreactivity in the tumor biopsies...

OBJECTIVE: To report the CNS syndromes of patients ≥60 years of age with antibodies against neuronal surface antigens but no evidence of brain MRI and CSF inflammatory changes. METHODS: This was a retrospective clinical analysis of patients with antibodies against neuronal surface antigens who fulfilled 3 criteria: age ≥60 years, no inflammatory abnormalities in brain MRI, and no CSF pleocytosis. Antibodies were determined with reported techniques. RESULTS: Among 155 patients ≥60 years of age with neurologic syndromes related to antibodies against neuronal surface antigens, 35 (22...

We assessed the effect of three different indices of urban built environment on allergic and respiratory conditions.This study involved 2472 children participating in the ongoing INMA birth cohort located in two bio-geographic regions (Euro-Siberian and Mediterranean) in Spain. Residential surrounding built environment was characterised as 1) residential surrounding greenness based on satellite-derived normalised difference vegetation index (NDVI), 2) residential proximity to green spaces and 3) residential surrounding greyness based on urban land use patterns...

REVIEW

The discovery, in 2010, of autoantibodies against the extracellular proteins LGI1 and Caspr2 facilitated a change of view regarding the clinical importance of voltage-gated potassium channel (VGKC) antibodies. Currently, these antibodies are all classified as VGKC-complex antibodies, and are commonly considered to have a similar clinical value. However, studies from the past few years show that the immune responses mediated by these antibodies have differing clinical relevance. Here, we review the clinical importance of these immune responses in three settings: patients with anti-LGI1 antibodies, patients with anti-Caspr2 antibodies, and patients with antibodies against the VGKC complex that lack LGI1 and Caspr2 specificity...

OBJECTIVE: To report the presentation, main syndromes, human leukocyte antigen (HLA) association, and immunoglobulin G (IgG) subclass in the anti-IgLON5 disease: a disorder with parasomnias, sleep apnea, and IgLON5 antibodies. METHODS: This was a retrospective clinical analysis of 22 patients. The IgG subclass was determined using reported techniques. RESULTS: Patients' median age was 64 years (range 46-83). Symptoms that led to initial consultation included sleep problems (8 patients; 36%), gait abnormalities (8; 36%), bulbar dysfunction (3; 14%), chorea (2; 9%), and cognitive decline (1; 5%)...

BACKGROUND: Mammalian target of rapamycin inhibitors may confer cardioprotective advantages, but clinical data are limited. METHODS: In the open-label ELEVATE trial, kidney transplant patients were randomized at 10 to 14 weeks after transplant to convert from calcineurin inhibitor (CNI) to everolimus or remain on standard CNI therapy. Prespecified end points included left ventricular mass index and, in a subpopulation of patients, arterial stiffness as measured by pulse wave velocity...

REVIEW
Josep Dalmau, Christian Geis, Francesc Graus
Investigations in the last 10 years have revealed a new category of neurological diseases mediated by antibodies against cell surface and synaptic proteins. There are currently 16 such diseases all characterized by autoantibodies against neuronal proteins involved in synaptic signaling and plasticity. In clinical practice these findings have changed the diagnostic and treatment approach to potentially lethal, but now treatable, neurological and psychiatric syndromes previously considered idiopathic or not even suspected to be immune-mediated...

OBJECTIVE: To report the main syndrome of dipeptidyl-peptidase-like protein 6 (DPPX) antibody-associated encephalitis, immunoglobulin G (IgG) subclass, and the antibody effects on DPPX/Kv4.2 potassium channels. METHODS: A retrospective analysis of new patients and cases reported since 2013 was performed. IgG subclass and effects of antibodies on cultured neurons were determined with described techniques. RESULTS: Nine new patients were identified (median age 57 years, range 36-69 years)...

OBJECTIVE: To identify cell-surface antibodies in patients with neuromyotonia and to describe the main clinical implications. METHODS: Sera of 3 patients with thymoma-associated neuromyotonia and myasthenia gravis were used to immunoprecipitate and characterize neuronal cell-surface antigens using reported techniques. The clinical significance of antibodies against precipitated proteins was assessed with sera of 98 patients (neuromyotonia 46, myasthenia gravis 52, thymoma 42; 33 of them with overlapping syndromes) and 219 controls (other neurologic diseases, cancer, and healthy volunteers)...

We assessed the outcome of patients with drug resistant epilepsy and neuronal antibodies who underwent epilepsy surgery. Retrospective study, information collected with a questionnaire sent to epilepsy surgery centers. Thirteen patients identified, with antibodies to GAD (8), Ma2 (2), Hu (1), LGI1 (1) or CASPR2 (1). Mean age at seizure onset: 23 years. Five patients had an encephalitic phase. Three had testicular tumors and five had autoimmune diseases. All had drug resistant temporal lobe epilepsy (median: 20 seizures/month)...

REVIEW
Josep Dalmau
Investigations during the last 10 years have revealed a group of disorders mediated by antibodies against ion channels and synaptic receptors, which cause both neurologic and psychiatric symptoms. In this review, I discuss the process of discovery and immunologic triggers of these disorders, and use anti-NMDA receptor encephalitis to emphasize the importance of understanding the underlying physiopathologic mechanisms in those diseases. A better knowledge of these mechanisms reveals points of convergence with other disorders (e...
